본 고안은 냉동실의 급속냉동(쾌속냉동)방식을 채택하고 있는 이른바 직냉식 냉장고에 있어서, 냉동실에 -1℃, 5℃의 온도감지 센서를 별도로 설치하여 기존에 설치된 냉동전용 스위치를 조작하여 냉장실의 냉각라인을 폐쇄시켜준 다음 냉동실의 내부온도를 필요에 따라 -1℃ 또는 5℃로 셋팅시켜 냉동실의 실내온도를 냉장실의 온도와 같게 한 냉동실을 냉장실로 절환시켜 사용할 수 있도록한 직냉식 냉장고의 냉동실 냉장 절환 장치에 관한 것이다.The present invention is a so-called direct-cooling refrigerator adopting the freezing method of rapid freezing (quick freezing), in which a temperature sensing sensor of -1 ° C and 5 ° C is separately installed in the freezing room to operate the existing freezing switch for cooling the freezing room. Close the line and set the freezer's internal temperature to -1 ℃ or 5 ℃ as needed to switch the freezer compartment to the freezer compartment so that the freezer compartment's room temperature is the same as that of the freezer compartment. Relates to a device.

일반적으로 소위 직냉식방식이 냉장고에 있어서는 콤푸레샤에 의하여 순환하는 냉각라인 1개의 전자변을 통하여 병열로 접속되어 냉장실과 냉동실로 각각 순환되게 하되, 냉장실로 우선 순환되게 한 다음 냉동실로 순환되게 하여 냉동을 하게되며, 필요에 따라서는 전자변 작동에 의하여 냉장실 라인을 폐쇄하고 냉동실로만 냉매가 순환되게 하여 냉동전용이나 급속냉방식동(쾌속냉동)을 행하도록 하는 방식으로 구성되는 냉장, 냉동의 각각 분리된 냉각 시스템으로 구성되어 있는 것이다.In general, the so-called direct-cooling type in the refrigerator is connected in parallel through one electronic valve of the cooling line circulated by the compressor to be circulated to the refrigerating compartment and the freezing compartment, respectively, circulated first in the refrigerating compartment and then circulated to the freezer compartment to freeze. If necessary, the refrigeration and refrigeration systems, which are configured in such a way as to close the refrigerating compartment line by electronic valve operation and allow the refrigerant to be circulated only to the freezing compartment, to perform exclusive refrigeration or rapid freezing (fast freezing). It is composed.

그러나 상기와 같은 직냉식 냉각방식에 있어서는 냉장실의 냉각라인을 폐쇄하고 냉동실의 냉각라인만을 가동시켜 -40℃까지 급속 냉각시켜 줄수 있는 효과와 냉장실과 냉동실의 냉각라인을 분리시켜 가동시켜 주어 절전의 효과를 기대할수는 있으나, 냉동실을 냉동실 전용으로 밖에 사용할수 없는 관계로 동절기등과 같이 냉장실만 필요하고 냉동실의 가동이 필요없는 경우에는 냉장, 냉동실이 동시에 가동되어 불필요한 전력이 소모되는 등의 문제점과 이에 따라 그 기능이나 용도가 한정되어 버리는 불편이 있었으며, 현재 등장하고 있는 직냉 방식의 냉장고에 설치된 냉동전용의 기능(냉장실 OFF기능)은 단순히 급속냉동시 조작하는 것에 불과하여 상기와 같은 불편이 많은 등의 여러가지 결함이 있었다.However, in the direct cooling system as described above, the cooling line of the refrigerating compartment is closed and only the cooling line of the freezing compartment is operated to rapidly cool down to -40 ° C. It can be expected, but since the freezer can only be used for freezers, only the freezers are needed, such as winter, and when the freezers do not need to be operated, the refrigerators and freezers are operated simultaneously, consuming unnecessary power. The functions and uses have been limited, and the functions for freezing only (freezer OFF function) installed in the direct-cooling type refrigerators that are currently appearing are simply operated at the time of quick freezing, and thus many inconveniences such as There was a fault.

본 고안은 상기와 같은 결합을 해소하기 위하여 상기와 같은 직냉방식의 냉장고에 있어서, 냉동실의 실내온도는 -1℃~5℃정도로 유지시켜 냉동실을 냉장실로 절환사용할 수 있도록한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in order to eliminate the coupling as described above in the refrigerator of the direct cooling method as described above, the room temperature of the freezer compartment is maintained at about -1 ℃ ~ 5 ℃ to be used to switch the freezer compartment to the refrigerating compartment, attached drawings When described in detail as follows.
